3 hours ago This formula is for right triangles only! The sides, a and b, of a right triangle are called the legs, and the side that is opposite to the right (90 degree) angle, c, is called the hypotenuse. This formula will help you find the length of either a, b or c, if you are given the lengths of the other two. These are called Pythagorean triples.

What is the midpoint formula of a triangle?

You do this in four steps:

  • Adjust the drawing compass to swing an arc greater than half the length of any one side of the triangle
  • Placing the compass needle on each vertex, swing an arc through the triangle's side from both ends, creating two opposing, crossing arcs
  • Connect the points of intersection of both arcs, using the straightedge
